Having reviewed the drilling performance to date, and the geological information from cuttings, we have decided that the first well will now be the production well. This is the more important well of the two as it will provide crucial information about the geology and temperature at our target depth, and it is imperative that we complete it as soon as possible.

We will continue drilling UD-1 at a diameter of 12 ¼” to  a depth of about 4,000m and then run the last of the three casing strings. Then we will finish the hole at a diameter of 8 ½” before running geophysical logs and carrying out a short period of testing. This should be completed by the end of March, after which we will skid the rig and begin drilling UD-2.
